The start frame delimiter found in the Ethernet frame is A preamble and begin body delimiter are a part of the packet on the bodily layer. The first fields of every body are locations and supply addresses.
What is the cause of the body delimiter?Frame delimiting, Addressing, and Error detection. Frame delimiting: The framing procedure affords essential delimiters which might be used to pick out a set of bits that make up a body. This procedure affords synchronization among the transmitting and receiving nodes.
The Preamble (7 bytes) and Start Frame Delimiter (SFD), additionally referred to as the Start of Frame (1 byte), fields are used for synchronization among the sending and receiving devices. These first 8 bytes of the body are used to get the eye of the receiving nodes.

A video game controller contains the buttons: A, B, X, Y. When the player presses A their character Jumps. When the player presses BY their character Crouches. When the player presses X their character Punches. When the player presses Y their character Flies. When the player presses anything else Pause menu shows up Assume your program contains a variable named button that holds a character which indicates the button the player has pressed. Write the switch statement that displays a message explained the user the action that was taken.
Answer:
Explanation:
The following switch statement takes in the variable button as a parameter and outputs a statement saying what the character did due to the button being pushed.
switch (Character.toLowerCase(button.charAt(0))) {
case 'a': System.out.println("Your character has Jumped"); break;
case 'b': System.out.println("Your character has Crouched"); break;

You have been given an encrypted copy of the Final exam study guide here, but how do you decrypt and read it???
Along with the encrypted copy, some mysterious person has also given you the following documents:
helloworld.txt -- Maybe this file decrypts to say "Hello world!". Hmmm.
hints.txt -- Seems important.
In a file called pa11.py write a method called decode(inputfile,outputfile). Decode should take two parameters - both of which are strings. The first should be the name of an encoded file (either helloworld.txt or superdupertopsecretstudyguide.txt or yet another file that I might use to test your code). The second should be the name of a file that you will use as an output file. For example:
decode("superDuperTopSecretStudyGuide.txt" , "translatedguide.txt")
Your method should read in the contents of the inputfile and, using the scheme described in the hints.txt file above, decode the hidden message, writing to the outputfile as it goes (or all at once when it is done depending on what you decide to use).
Hint: The penny math lecture is here.
Another hint: Don't forget about while loops...
Mac hint: use encoding="utf-8" in your file open functions, like this:
Mac hint: use encoding="ascii" in your file open functions, like this:
fin = open(input_file,"r",encoding="ascii")
Answer:
You use a decoder

how many stages needed to have powerful amplifier?
Power amplifier stages in a real circuit. Circuit diagram of a three stage practical audio power amplifier is shown in the figure below. Small signal transistor Q1 and its associated components form the voltage amplification stage.
Answer:
Generally you should pick an amplifier that can deliver power equal to twice the speaker's program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.

Suppose a program is supposed to reverse an array. For example, if we have the array arr = {1, 2, 3, 4, 5}, after reversing the array we would have arr = {5, 4, 3, 2, 1}.
Most of the code for the program is shown here:
Const int SIZE = 5;
int arr[SIZE] = {1, 2, 3, 4, 5};
int firstindex =0, lastindex = SIZE-1, temp;
1 _______________________________
{
temp = arr[firstindex];
arr[firstindex] = arr[lastindex];
arr[lastindex] = temp;
firstindex++;
lastindex--;
}
All of the following options below could be correctly inserted at line 1 in the code shown above EXCEPT:
a. while(firstindex < lastindex)
b. while(firstindex <= lastindex)
c. for(int i=0; i<(SIZE/2-1); i++)
d. for(int i=0; i<(SIZE/2); i++)

Write the simulate method, which simulates the frog attempting to hop in a straight line to a goal from the frog's starting position of 0 within a maximum number of hops. The method returns true if the frog successfully reached the goal within the maximum number of hops; otherwise, the method returns false. TheFrogSimulationclass provides a method calledhopDistancethat returns an integer representing the distance (positive or negative) to be moved when the frog hops. A positive distance represents a move toward the goal. A negative distance represents a move away from the goal. The returned distance may vary from call to call. Each time the frog hops, its position is adjusted by the value returned by a call to thehopDistance method. g
Answer:
Explanation:
The following code is written in Python. It creates the simulate method which takes in an argument for the max number of hops and the goal distance. Then it loops the number for the max number of hops and asks the user for a hop input using the hopDistance() method (which was not included so it was made, this can be removed if wanted). Then it updates position. If after the max hops goal was reached it returns True, otherwise it returns False.
def simulate(max, goal):
position = 0
print("Goal is " + str(goal))
for x in range(max):
hop = hopDistance()
position += int(hop)
if position >= goal:
return True
else:
return False
def hopDistance():
return input("Frog Hop Distance this hop: ")
print(simulate(4, 20))

When the function below is called with 1 dependent and $400 as grossPay, what value is returned?
double computeWithholding (int dependents, double grossPay)
{
double withheldAmount;
if (dependents > 2)
withheldAmount = 0.15;
else if (dependents == 2)
withheldAmount = 0.18;
else if (dependnets == 1)
withheldAmount = 0.2;
else // no dependents
withheldAmount = 0.28;
withheldAmount = grossPay * withheldAmount;
return (withheldAmount);
}
a. 60.0
b. 80.0
c. 720.0
d. None of these
Answer:
b. 80.0
Explanation:
Given
[tex]dependent = 1[/tex]
[tex]grossPay = \$400[/tex]
Required
Determine the returned value
The following condition is true for: dependent = 1
else if (dependnets == 1)
withheldAmount = 0.2;
The returned value is calculated as:
[tex]withheldAmount = grossPay * withheldAmount;[/tex]
This gives:
[tex]withheldAmount = 400 * 0.2[/tex]
[tex]withheldAmount = 80.0[/tex]
Hence, the returned value is 80.0

Write a class called MonetaryCoin that is derived from the Coin class presented in Chapter 5 (the source code for Chapter 5 examples is available via Moodle). [6 pts] Store one integer and one float in the MonetaryCoin that represent its value and weight in grams, respectively. Add a third variable of your choice (related to a coin, of course) and use self-descriptive variable names for all three variables. Pass the values to the constructor in MonetaryCoin and save them to your variables.
Answer:
Explanation:
The following Java code creates the MonetaryCoin class that extends the Coin class. It then creates three variables representing the MonetaryCoin object which are its value, weight, and coinYear. These are all passed as arguments to the constructor and saved as instance variables.
public class MonetaryCoin extends Coin {
int value;
float weight;
int coinYear;
public void MonetaryCoin(int value, float weight, int coinYear) {
this.value = value;
this.weight = weight;
this.coinYear = coinYear;
}

Do exercises as follows:
a. Enter a whole number from keyboard, a while loop should calculate a sum of all numbers from one to that number that you entered
b. Enter a numeric score - grade of a test, your program should print a corresponding letter grade that matches the score.
For example, if you enter 89.3, the program should display "B", and if you enter 95.7, then the program displays "A"
Answer:
Explanation:
The following Java program asks the user for a number to be entered it and uses a while loop to sum up all the numbers from 1 to that one and print it to the console. Then it asks the user for a grade number and prints out the corresponding letter grade for that number.

total_rainfall += int(info[1])
average = total_rainfall / 3
